| 摘 要： | 采用调查收集、取样分析等方法对环神农架地区1700多个耕层土壤样品的pH、有机质和土壤养分进行了分析。结果表明:环神农架地区植烟土壤pH、有机质、碱解氮、速效磷和有效钾含量的一般范围分别为5.02~7.92,11.19~52.24 g/kg,58.69~216.20 mg/kg,3.92~39.00 mg/kg和51.84~332.14 mg/kg,以土壤pH变异最小,土壤速效磷含量变异最大。环神农架地区植烟土壤pH 5.5~7.5的样品占总数的82.5%,多数土壤pH适宜优质烟叶生长,土壤有机质含量和氮含量总体较高,磷和钾含量相对较低。以该区烤烟产值为目标的土壤养分丰缺状况评价结果表明,环神农架地区绝大多数烟区处于供氮能力中等和高的范畴,土壤供磷和钾的能力则多处于中等和低的范畴;土壤供钾能力呈现出明显的区域分布特征,土壤供氮和供磷能力地域分布不明显。
